Does that mean that you have no major, or what?

Complex analysis is used extensively in control theory. However unlikely it sounds, stuff like argument principle finds applications, check out stability criterions of Nyquist.

Real analysis is a prerequisite for both complex, functional and fourier analysis, where the last two are pretty much the most applicable pieces of abstract mathematics that I've seen. Modern methods of numerical approximation are justified by functional analytic methods. You must have heard of the solutions to the heat equation that Fourier proposed. Fourier transform is absolutely fundamental in signal processing, it's fair to say that you always want to compute the Fourier transform of your data.

It's algebra that is used in cryptography. It's been fairly recently discovered how stuff like modules and Gröbner bases can be used to construct cryptosystems, more exactly I am talking about the Polly Cracker type. Famous RSA is a special case of this.

If you deny it then tell me what is 1-0.999.... ?
